10201 XL PV fuses
High-speed PV fuse with 315 A rating delivers rapid interruption at 1500 Vdc, reducing arc energy and protecting both modules and inverters, which translates to lower repair costs and less downtime. The device’s Class gPV designation supports safe DC protection in solar installations, while its 100 kAIC interrupt rating provides a robust safety margin for fault events in utility-scale strings. A top fuse status indicator enables quick verification during routine checks, minimizing on-site time and labor costs. The 217 mm length and blade-only connections simplify mounting and retrofit into existing SD3L-S-PV XL fuse bases, improving installation efficiency. With 52 W watt losses, thermal performance stays predictable, preserving overall system efficiency. CE RoHS, IEC 60269, UL Listed, and CSA Certified certifications reinforce compliance across markets.
